France August 22, 1932 1 Claim.

At the present time the known vises have two parallel jaws or cheeks, in other words the jaws, at whatever distance they are from each other, always remain parallel to each other, so that they are of no use for an oblique or other grip.

The known vise with a movable jaw has not given the solution of the problem.

It was therefore of importance to construct rotary and detachable jaws enabling any section or profile to be gripped, and this construction will thus provide the user with a universal vise without having recourse to supplementary accessories and retaining the advantages of the vise with parallel aws.

In the attached drawings showing the object of the invention by way of example:

Figure '1 is a plan-view of a vise for bench use, equipped with the rotary and detachable jaws (with a key in position for a parallel grip).

Figure 2 is an elevation-view with partial section of a bench vise equipped with the rotary and detachable jaws (with a. key in position for a parallel grip).

Figure 3 is a diagrammatic section through the axis 1- -2. 7

Figure 4 is a diagrammatic view of the jaws for the parallel grip.

Figure 5 is a diagrammatic view of the jaws for gripping a round object of small diameter.

Figure 6 is a diagrammatic view of the jaws for the gripping of a round object of intermediate diameter.

Figure 'l is a diagrammatic view of the jaws for gripping 'a round object of medium diameter.

Figure 8 is a diagrammatic view of the inverted jaws for gripping a round object of large diameter.

Figure 9 is a diagrammatic view of the jaws for gripping any triangle.

Figure 10 is a diagrammatic view of the jaws for gripping an object with an inclined face (one of the jaws being removed).

Figure 11 is a diagrammatic view of the jaws for gripping a round or other bar placed vertically.

Figure 12 is a diagrammatic view of the jaws for gripping a T iron or other similar objects.

Figure 13 is a diagrammatic view of the jaws to gripping'a U iron (the two jaws being inverted) Figure IQ is a diagrammatic view of the jaws for gripping a cut-out shape.

Figure 15 is a diagrammatic view of the jaws for gripping a triangular shape.

' Figure 16 is a diagrammatic view of the jaws for gripping an almost flattened triangle.

The invention is therefore essentially constituted by: two rotary and detachable jaws a hav* ing vertical, cylindrical tails b turning freely and without play in a socket of the boss 0, each boss 0 being placed symmetrically in respect of the axis of the carriage d carrying the rotary and detachable jaws a. r

The release of the jaws (to pesmit of removal) is effected by removing the locking pin e placed transversely and fitting into a suitable circular groove on the vertical cylindrical tail bi Each jaw a has first a large face a: for the parallel grip and then a perpendicular face y for gripping round objects of medium diameter, while a small face 1) serves for gripping round objects of small diameters.

The carriage d is controlled in the usual way and by one of the known means.

In any case whatsoever the jaws a are always supported by the fixed or movable part of the vise, their action consisting only of the replacement of one of the cheeks, the other cheek being used without change.

For the parallel grip and-in order to avoid the permanent rotation of the jaws a, a key e is inserted between the lower face of the jaws a and a shoulder part 1 of the carriage d; this key e holds thus the two jaws a .in a position parallel to the fixed cheek of the vise.

It is therefore sufficient to remove this key e p to give full liberty to the rotary jaws a thus enabling the gripping of all shapes or sections as shown in the diagrammatic figures.

Fpr gripping certain shapes one of the rotary jaws a can even be removed.

It is appropriate to note the full interest of the invention which can be applied to all'types of hand ormachine-tool vises and eliminates all of the costly fittings made up to the present for gripping objects of a special section.

It is of course understood that the present construction is ofi'ered only by way of example of one of the methods of application of the invention, the details of manufacture or of construction being capable of variation without differing from the essential characteristics of the invention as defined by the appended claim.

What I claim and desire to secure by letters Patent of the United States is:-

In a vise having a fixed jaw, a pair of free and swiveling movable jaws each arranged in clamping relationship to said fixed jaw and having three gripping faces of different length and surface dimensions disposed at right angles to each other and individually adapted to be opposed to said fixed jaw, a cylindrical tail formed on each movable jaw, whereby to render it possible to effect changes in the position of the gripping faces relatively to the fixed jaw, and means for closing said movable jaws upon said fixed jaw, whereby to grip articles of difiering section between said fixed and movable jaws.
